Abstract

PURPOSE:To soften a bending angle of the knee by mounting a fitting revolving around different circle centers, and by mounting a pedal on a holes thereof for rotation. CONSTITUTION:A fitting 1 revolving around different circle centers is mounted on a crank 2, while a pedal 5 is mounted on a mounting hole 3. The length of the crank 2 is shortened by the same length of the fitting 1 revolving around different circle centers, while the revolving outer circumference of the pedal 5 applied is turned around different circle centers similar to a type of 18-19 nights of ages of the moon, and the crank 2 is rotated without adding excessive load to the knee.
